Does anyone recognize this Tubular Brass Floor Lamp?  

Maybe Italian. Looks a lot like Mario Arnaboldi "Mira" lamp

Thanks Charlie! The lamps definitely do look similar. After doing some research based on your info, I found that the "MIRA" lamp was only in production for one year. I am thinking the one I have may be a knock off from the same early 80s period. The MIRA lamp had an on/off switch integrated into the base of the lamp. The one I have has a round disk foot switch on cord.
The brass tube articulating mechanisms look nearly identical on mine...but the base is a bit off.
Thanks for your response.

I like your lamp a lot.
"MIRA" lamp was indeed in production for only a year or so and that is what makes your lamp interesting. It may be some kind of prototype
It might be a good idea to try to contact Mario Arnaboldi through his firm Arnaboldi & Partners:

(you never know ...)

You are correct. One Never knows! If nothing else, the will become aware that someone was copying his design. 😉
I sent some photos off to their studio. I will let you know if I get a response.
Thanks again for pointing me in the right direction.

Not at all.
I am very curious about their response.
